ionogram
ionogram (aɪˈɒnəʊgræm) [f. iono- + -gram.] 1. A record of radio pulses received by an ionosonde following their reflection by the ionosphere.1955 Sci. Amer. Sept. 128/2 To make an ionosonde record (ionogram) the transmitter and receiver are tuned rapidly through a range of frequencies. The echoes re... Oxford English Dictionary

Ionospheric sounding
Oblique sounders use a transmitter at one end of a given propagation path, and a synchronized receiver, usually with an oscilloscope-type display (ionogram The ionogram display shows the effective altitude of the ionospheric layer as a function of frequency.
